Interestingly, stronger communication, which was related to chemo‐attraction (CCL2‐CCR2, CCL2‐ACKR1, CCL11‐ACKR1) and angiogenesis promotion (VEGF‐VEGFR), from pericytes to endothelial cells and tumour cells was identified in the solid components than in the GG components (Figure 5L). Here, KDR is linked to neoplasm.
